Senior Unity Programmer (Physics & AI)

Full-time | Remote(Germany-based)

Salary: €5400 -- €6300 per month (depending on experience & fit)

About Us

We're a small remote studio based in Germany working on our debut title Kinstrife. Our goal is to build not just a game, but both a franchise and a sustainable team for years to come. We run on trust & autonomy rather than hierarchy, value iteration over perfection, and focus on what truly matters to players. We're currently scaling up our team and are looking for people who share our approach to making games

Role Description

Join us as a Senior Programmer to spearhead the development of one of Kinstrife's most ambitious features: our physics-based combat engine. You will be pushing the boundaries of Unity 6 and DOTS, building a performant solution capable of handling large-scale battles with many dozens of physically simulated characters. This is a systems-heavy role for someone who loves the intersection of 3D math, physics and high-performance C#. If you have a knack for systems-thinking and love optimizing large-scale simulations where every microsecond matters, we'd love to hear from you.

Your tasks include:

• Own and optimize our DOTS-based combat and character systems (Jobs & Burst), ensuring large-scale battles remain performant across target platforms
• Lead the expansion of our physics-animation system, collaborating with animation & combat gameplay developers on new feature development
• Design and implement scalable low-level AI systems, e,g, context steering for navigation and group behaviors like formations and tactical coordination
• Profile and optimize gameplay code to maintain smooth framerates during intensive combat scenarios with many dozens of combatants
• Collaborate with junior/mid-level programmers to build higher-level features on top of your systems

Qualifications

• 7 years in game development, with a focus on systems, AI or physics programming in C#
• Strong understanding and hands-on experience with Unity's Data-Oriented Tech Stack (DOTS), i.e. ECS, Burst and the Job System
• Strong proficiency in 3D math and the application of physics for real-time gameplay
• Ability to coordinate with other gameplay programmers to bridge the gap between physically simulated behaviors and kinematic animation/logic
• Fluent in English with the ability to clearly document systems and collaborate effectively in a fully remote, asynchronous environment
• Highly self-driven with a systems-oriented mentality. You work best when given context and goals, rather than daily task lists

Bonus Points

• Experience with Unity 6 and its latest features
• Experience with physics animation
• Experience with AI paradigms & frameworks
• Experience with numerics, particularly realtime simulations
